out of curiosity, what are the differences aside from pistons/rods on the vg30de vs vg30dett reason i ask is because i wanted to buy a long block and work on it to rebuild but its easier to find a vg30de longblock for a lower price than a vg30dett long block, i figure if i'm swapping out the pistons/rods and going to port/polish the heads anyways wouldn't it theoretically be the same? unless that is the vg30de long block doesn't have connections for the water pipes and stuff for the turbos?
